Deere lawn tractor fuel pump bad?


Hi...

I just went out to start my L118 Deere lawn tractor and it wont start. Replaced the fuel pump and still no go. Pulled the line off the outlet of the fuel to see if there is gas coming out and nothing is coming out.

I am planning to replace the fuel pump but is there anything else I should check ahead of that?

Thanks

Sure. Check the fuel filter, especially if you use methanol laden gasoline. Also, does it actually have a fuel pump or is it gravity fed? Just curious.

I actually replaced the filter already....Figured that was easy and cheap. Pretty sure its a fuel pump... Looks like this and the engine is a Briggs Intek 20

That is an impulse fuel pump, common on small engines. Are you sure you hooked up the 3 tubes correctly? Prime the pump and spray some gas in carburator with air filter removed. Now start engine.

I have not even tried replacing the pump yet. I have not bought it yet. My first step was replacing the fuel filter and that did not work. Figured I would ask here on the forum first before ordering a new pump or stopping at the mower shop.

Its a good suggestion... let me try getting some gas in the carb as you suggested. I only tried removing the line from the outlet of the pump and tried to see if I could get gas to pump out into a can. Did not work....I am not sure how best to get to the carb. I seel the fuel line go under the housing for the air filter. I will have to check again and see if its more obvious.

I also loosened the gas cap in case it no air was flowing into the tank and there was a vacuum.

Thank you

I don't know all of the JD model lines but does your carburetor bowl have an electrical wire connected to it? That is a fuel shut off solenoid and can foul. Also, I'm kinda surprised a JD engine would use a B&S pump but, again, not familiar with all of their lines.

Hmm...Not sure.... I think I recall a solenoid being called out on a parts list. I would need to check. I know its a B&S engine. Its not a high end Deere, just the lawn tractor, a step up from the L110 and its about 14 years old. Engine is B&S Intek 20

According to the Interweb, it does have a carb solenoid, but if you're not getting fuel it's not likely the problem. If there is gravity flow from the line out of the tank, it is likely that either the pump is pooched or it's not getting vacuum to operate it. Maybe check for an intact vacuum line to the pump.

Re: Deere lawn tractor fuel pump bad?


So... figured I would try again... outlet pumped gas into a can when I tried to start it. Hooked up fuel line again and it started right up.

Couple questions.

How do I check this solenoid and where is it and how does it work? Does it turn on the fuel pump? Or is it in line with the fuel and opens and closes?

Also the pump if the vac line had a hole, how do I check that? It goes down to the OHV.

My guess is still that the fuel pump is flakey, but could use some insight how to eliminate the solenoid and other items.

Thanks

Re: Deere lawn tractor fuel pump bad?


The Interweb offers a few links - there are probably others.


The carb solenoid is a fuel shut-off:





Other than a visual check of the vacuum line, try this:
